How do you convert Mass Flow Rate to Velocity?

Answer 1

when you have the vescosity to react with the liquid or the substance in the being of the making

Volumetric flow is L^3/T, a cubic length divided by time (cubic meters per second, for example.) Velocity is L/T (meters per second or miles per hour). To get velocity from volumetric flow, you divide the volumetric flow by the cross-sectional area (L^2) of whatever the liquid is flowing through. If you have .5 ft^3/s of water flowing through a pipe with a 1.5 inch diameter, convert 1.5 inches to feet: 1.5/12 = .125 ft, then find the cross-sectional area: (pi/4)(.125^2) = .01227 ft^2. Then .5 ft^3/s by the area and get 40.7 ft/s, which is about 27.75 mph.

Answer 2

The relationship of mass flow rate of to volumetric flow rate is

m-dot=V-dot/v

where m-dot is the mass flow rate, v is the specific volume of the water, and V-dot is the volumetric flow rate.

Answer 3

mass flow rate and volume flow rate both are come from conservation of mass equation.

if assumption are incompressible fluid and fixed control volume surface ,it means density and volume become constant ,result equation show volume flow rate .it doesn't matter flow is steady or unsteady.

another case if take assumption as steady flow than result show us mass flow rate.

so before convert mass flow rate into volume flow rate we have to take assumptions.

dm=integration(density*dv) (show mass flow rate) ;where v=volume

dv=integration(A.dV) (show volume flow rate)

;V=velocity vector & A=area of surface (direction is perpendiculr to surface toward outside) here this is dot product

dm=integration(density(A.dV))

Answer 4

You need to use the formula Q = AV.

Q = flow rate, A = Area, V = velocity.

A needs to be calculated. For example if a fluid is flowing through a pipe of Diameter 10 cm then its radius = 5 cm. Its area will be = pi. r. r

Now put the values in the formula. V = Q/A

Flow rate divided by the area will give the velocity of the fluid. You have thus converted flow rate to velocity. Area can change depending on the shape of the object through which the fluid is flowing.

Thank you for reading.

Answer 5

To convert mass flow rate to velocity, you need to know the cross-sectional area through which the mass is flowing. Then, you can use the formula velocity = mass flow rate / (density * cross-sectional area) to calculate the velocity. The units for mass flow rate need to be consistent with the units of density and cross-sectional area for this conversion.

Answer 6

you divide the volume by time. time how long it takes for the fluid to flow.

Answer 7

Orfice meters,venturi meters, rotameters, and displacement meters are used extensively in industrial operations for measuring the rate of liquid flow.

Answer 8

you take your unit of measurement ( usually volume ) and divide it by seconds. ML/S

Answer 9

division of mass flowrate [e.g. kg/s] by density [e.g. kg/l] gives the volumetric flowrate [e.g. l/s]
